Magpas Helimedix said they were requested to attend by an ambulance crew at 4pm after the man collapsed, struggled to regain full consciousness and appeared disorientated.

“The Magpas team anaesthetised the patient at the scene and then accompanied him to Queen Elizabeth Hospital King’s Lynn, in a land ambulance, for further investigation,” Magpas said in a statement. “On arrival at the hospital, the man was in a serious but stable condition.”
